2 results about "Aprepitant" patented technology

Disclosed are a pharmaceutical composition, an aprepitant injection, and an aprepitant freeze-dried powder injection. The pharmaceutical composition comprises aprepitant, a primary stabilizer, and a secondary stabilizer, wherein the primary stabilizer comprises sodium deoxycholate and the secondary stabilizer comprises povidone. The aprepitant injection can be administered by injecting. The formulation uses a largely reduced amount of excipients, and is less irritative to an injection site, less prone to cause a hypersensitive reaction, and thus safer when being used by a patient. The formulation has good stability and can be stored and transported at room temperature, largely reducing production, storage, and transportation costs.

Provided is a process for preparing an emulsion having an oil phase containing an emulsifier, an oil, a drug, and a co-emulsifier, and an aqueous phase containing water, a tonicity agent, and a pH modifier, without removing excess co-emulsifier after emulsification. The process includes emulsifying an oil phase containing an oil, aprepitant, an egg lecithin, and ethanol, and an aqueous phase containing water, sucrose, and oleic acid or salt thereof, without removing ethanol after emulsification. The drug is added to the oil phase as a dry mixture containing the drug and a co-emulsifier (e g., ethanol).
